摘　　要：签密就是能够在一个逻辑步骤内同时完成数字签名和加密两项功能,比传统的"先签名后加密"有更高的效率.结合多重签名和签密的思想提出了一种多重签密模型,模型中的签名和加密技术可以灵活选取,使其不仅可以实例化为对单个和一组消息的多重签密方案,还能实例化为多人才能解签密的多重签密方案.Signcryption is a new cryptographic technology, which simultaneously fulfills both the function of digital signature and public key encryption in a logically single step, and more efficient than the traditional 'signature followed by encryption' approach. In this paper we propose a mutli-signcryption model based on multi-signature and signcryption, and various signatures and encryptions can be chosen flexibly in the model. At the same time, the model can be instantiated into the multi-signcryption scheme to a single or a group message and the multi-signcryption scheme which can only be decrypted by multi-receivers.
